I'm not worried about Auto-RX+ causing any damage. The engine is
running better then ever, and my
butt dyno is telling me that the block is benefiting from all these cleaning products.
So they're said to be engine safe and not showing a problem in the UOA but they also don't seem to be doing much cleaning to the underside of the valve cover, in an already clean engine. Nothing but cleaning by hand will clean that valve cover.
Your butt dyno isn't feeling a cleaner block, just a lighter wallet. I'm not trying to be a jerk, but I'm an admitted cheapskate that hates to see people spend money needlessly.
I respectfully disagree regarding my butt dyno. After 15 years of driving this thing, I could tell when it needed an oil change just by the way it drove
I feel my butt dyno is calibrated pretty good towards this engine and how she spins. I felt an improvement in performance after the first A-RX cleaning. I felt improvements are Kreen and I definitely felt improvements in engine performance after changing the spark plugs from the rear 3 cylinder banks after they've been in there for 120,000 miles (the front 3 were changed on time, after a 90k interval.) and I also noticed improvements in engine performance after the intake manifold was cleaned along with the throttle body.
I'm sure had I done compression testing along the way, I have no doubt that it would have shown improvements, as many have said about A-RX and Kreen but compression improvements is not my main goal during these tests.
My wallet is also not any lighter then before as I received a refund for the Kreen I used and got A-RX+ shipped to my door at no cost to me. $1.5 a quart for the PYB I used along the way isn't going to drain my bank account (got the oil during Kmart's clearance sales) and a few Mobil 1 oil filters bought for $6 a piece has been handing filtration duties. Thank you for the concern but my wallet is fine. Besides, I don't mind the credit card points
